That can put a serious hit on an area's economy. I know what it would do here. Southern ID has about 1/2 million cows within 100 miles of Twin Falls. The major products are cheese with a huge amount going to Chobani yogurt. ID is 3d in milk production behind CA and WI, quite a ways behind them, actually. I don't know how big dairies are in CA & WI, but in ID, the average dairy is 1200 cows with a few as large as 10,000.
Around here, if you're looking for rural property to buy, you want to spend considerable time looking at aerial photos to make sure the place isn't downwind of a large dairy. Some of the properties are for sale because they aren't livable.
